galvanizing Electro
Sharaxaad Gaaban:
Galvanizing Electro: sidoo kale loo yaqaan galvanizing qabow ee warshadaha, waa habka of samaynta labis, cufan oo si fiican u xidhan birta ama daaha dhigaalka daaha on dusha workpiece by electrolysis.
Marka la barbardhigo biraha kale, zinc waa mid raqiis ah oo sahlan in lagu dhejiyo.Waa dahaarka korantada ee ka-hortagga daxalka qiimo hoose.Waxaa si weyn loo isticmaalaa in lagu ilaaliyo qaybaha birta iyo birta, gaar ahaan si looga hortago daxalka atmospheric, iyo qurxinta.Tignoolajiyada dahaadhida waxa ka mid ah dahaadhidda qubayska (ama dahaadhidda deldelida), daminta foosto (ku habboon qaybo yaryar), dahaadh buluug ah, dahaadhay si toos ah iyo dahaadhay joogto ah (ku habboon silig iyo falin).
sifo
Ujeedada electro galvanizing waa in laga hortago walxaha birta ah inay daxaloobaan, wanaajiyaan caabbinta daxalka iyo nolosha adeegga birta, iyo kordhinta muuqaalka qurxinta alaabta.Birta waxa daxaloobaysa cimilada, biyaha ama ciidda marka uu wakhtigu kordho.Shiinaha, birta qudhuntay waxay xisaabisaa ku dhawaad toban meelood meel meel wadarta mugga birta sannad kasta.Sidaa darteed, si loo ilaaliyo nolosha adeegga birta ama qaybaheeda, galvanizing electro-ga guud ahaan waxaa loo isticmaalaa in lagu farsameeyo birta.
Sababtoo ah zinc ma fududa in lagu beddelo hawada qallalan waxayna soo saari kartaa filimka aasaasiga ah ee zinc carbonate ee jawi qoyan, filimkani wuxuu ka ilaalin karaa qaybaha gudaha ee dhaawaca daxalka.Xataa haddii lakabka zinc uu wax yeelo qaar ka mid ah, Zinc iyo birta ayaa isku darsami doona si ay u sameeyaan batari yar muddo ka dib, si matrixka birta uu noqdo cathode oo la ilaaliyo.Waxaa la soo gebogebeeyay in electro galvanizing uu leeyahay sifooyinka soo socda:
Waxay leedahay iska caabin wanaagsan oo daxalka ah, isku darka wanaagsan iyo isku midka ah, mana fududa in lagu galo gaaska daxalka ah ama dareeraha.
Sababtoo ah lakabka zinc waa saafi ah, ma fududa in lagu daxaleeyo aashitada ama deegaanka alkali.Si wax ku ool ah u ilaali jirka birta muddo dheer.
Waxaa loo isticmaali karaa midabyo kala duwan ka dib passivation chromate.Waxaa lagu dooran karaa iyadoo loo eegayo doorbidka macaamiisha.Galvanizing waa qurux iyo qurxin.
Daahan zinc wuxuu leeyahay ductility wanaagsan oo si fudud kuma dhici doono inta lagu jiro foorarsiga, maaraynta iyo saamaynta kala duwan.
